Experimenting with the format is fine and it might well be fun. The communication is, as always, frustrating: sideboarding is a "huge barrier to entry" but a second deck isn't? This type of thing -- similar to the constant citation of bo1 stats without acknowledging that Arena is set up to push people into bo1 -- just makes players worry the decisions have already been made.
Also think having 24/64 players at a high-level event be arbitrarily chosen streamers is pretty silly.
